, ,V-With the above -v (.)therends invention consists inthe matters hereinafter setforth,and; morefparticularly pointed; `o ,ut

in the appended claimgeference *beingr had to the accompanying drawing, in vvhich` Figure 1 is a perspective view of a device illustrative ofthe invention and showing the same as applied tothe intake manifold of an internal combustion engine; and

Fig. 2 is a .transverse vertical section.

ythroughthe device. o e

As shown in the drawing, 1 indicates the v riser pipe, to the lower end of which the usuall carbureter (not shown) is attached,

and 2 indicates the engine intakefrnanifold.

Interposed between the pipe 1 andl manifold Y or formed as a part of the upper end ofthe pipe as shown, is a casing 3 forming a chamy. ber, into the bottom of which the Vpipe opens.

Formed integral with the manifolda's shown or as a separate part, is acap, head 0r cover.: y, 4 for the casing l3,vvith the casing detachy* ablyA secured thereto by providing a vflange on the ca-sing having holes to receive bolts 5 which engage screw-threaded openings in` the cap. The cap is preferably formed with an interna-l shoulder 6 against which is seated andfsecured inV any convenient manner, a

lperforated plate or wire screen 7'which ex-l tends completely across the passage through thel manifold so that all ygaseous* mixturel passing to the manifold .will pass therefl through a`nd be thoroughly mixed thereby. l v v 1 t,

To further break up the ingoing charges from the carbureter, and provide a vcircuibroken up and tous path for the same, atube 8 arranged ax-Vv ially of the chamber 3, is seated in an annular seat 9 in the bottom of the chamber and :.55 surrounding thebore of the pipe 1, this tube forming an upward continuation of the pipe 1 to near the upper end 'of thef chamber 3.

f 'Fuel vapor and air passingfi-omi-the pipe l to the manifold Qis thus caused-to vtravel in a circuitous path, lpassing. to the upper end of the center tube 8,y through the Lopen# ings 14,5 thence'downwardl inthe annularv passage 16,? through Vjthe openings 15 and y,vvallsa :l space 17 being open atits upper end around the disk lland between it and Y then upwardv in theannular space v17 and out through'the Vcap linto the manifold. The

space in the annular passage 16 is ofslight-. ly'greater capacity than the capacity `of the tube 8 and the capacity lofthe outerlannular,v space or passage 17 is greater than that of I thepassage 16 so'that `the mixture of 'air and vapor expands from one passage vinto f the next, thus aiding'in the efficient mixing of'thetwo, and the mixtureas it passes 'theV screen 7 is again broken up Vand intermingled, yproducing a final mixture' entering the manifold havinglpractically no globules 'of liquid of a size to bek precipitated inpassing through Athe vvmanifold.y A highly explosive mixture is thus delivered to the engine; and any liquid fuel which may bel precipitated in the Vpassages 16 and 17 falls to the bot,-

Ytom thereofand will be swept out` vas theenginewarms up and itsspeed increases. The holes 14 andlbeing small, serve asia mul-v tiplicity of jet Aopenings from which; the

, construction andarrang'ement of partsl withf mixture issues into the next succeeding chamber' v,with yhigh, Velocity and in a jet,

thus .further breaking` up .and interiningling the air and uel. 'Y

Withthis particulariconstiiiction, the def `vice may be very cheaply manufactured;asi

the tubesS and 10 are merelyA lengths of pipe cutto length and perforatedto pro#H `Videthe holes 14 and V15, and these Vtubes are simply set iny pla-ce Vand secured in position Vby the 'securing of the disk 1l in place thereoii by the bolts Very efficient device for thepurpose is thus provided, and one wliichinaybe quickly'finstalled.

Obviously changes may be made in the in'VV the scope or" theappended claim Without departing` from thespirit *of the invention, and I do not,ytherefore,wishtofliinit Inyself to the 'particular foirlnuand arrangenient shown. Y
